This is important stuff - I did first grade twice, because I was a "slow starter" in a lot of ways. My mother had serious concerns about how well I'd do at school, for the first few years (even after being left back -- it didn't help that I was incredibly shy and didn't really want to interact with the teacher), but once I started reading I read voraciously, and got better & better at school as time went on, so by the end of HS and then in university I was at the top of my class generally. There's still a pile of stuff I wish I'd learned much, much earlier -- like "how to get good at something" (besides just muddling your way into it), and that the basics of skill acquisition apply to social skills as well... so now I'm explicitly teaching these things to my kids, along with a healthy dose of fun and silliness along the way.
